A. The length, width and shape of blocks shall take into account the need for adequate building site size and street width and shall recognize the limitations of the topography.

B. Size: No block shall be more than 530 feet in length between street corner lines unless it is adjacent to an arterial street or unless the topography or the location of adjoining streets justifies an exception. A block shall have sufficient width to provide for two tiers of building sites unless topography or the location of adjoining streets, or a similar constraint justifies an exception. Where existing street spacing is non-conforming, or a variance to the street spacing standards is proposed, a pedestrian and bicycle multi-use pathway shall be provided with spacing no more than 330 feet except where impracticable due to factors such as topography, environmental features, or existing development.

Block size for the use of the Local “Skinny” Street standard shall not exceed 330 lineal feet in any dimension without connection to street corner lines. However, where constrained by topography, environmental features, or existing development, the Local “Skinny” Street standard may be used in any roadway less than 2,400 feet in length and for which extension or connection to other streets is not possible.
